Well, I get its nature but it was definitely not an experience. Don’t let the pictures fool you, those pictures are a chance in a million that would be your experience. If you have money to spare go for it. A family of four is pricey to look at the stars in a bay. Also was told by our guide best time to go is warmer weather with warmer water like May - August. No photos added because nothing was seen.

This was definitely one of the highlights of our trip to Puerto Rico. Our guides were great, and they made everyone feel safe. Kayaking through a dark mangrove was magical, and it was fun to learn about the bioluminescent bay.

One of the coolest experiences of my whole life. Don’t miss this. It was incredible. Apparently, it was less “bright” than normal too. I’d go again in an instant.

Hosts are great! Bring bug spray and wear long sleeves. You will get wet waste down. Don’t need shoes, flip flops work fine. Get a waterproof case for your phone.

It is a cool experience - unfortunately we went with it being almost full moon so they had us cover with tarp but the tarp was too thin and didn't make it dark enough so we only saw a couple sparks. Thicker tarps would make it better as they can't control the moon.

This was a very good tour company and cool experience. We were lucky one of the tour guides hooked their boat to ours and helped tow us during the kayaking because it was a little difficult. We went one week before the full moon and had to use a tarp to see the bioluminescence. You could definitely see some but it’s not like the pictures. But the experience itself still makes it worth it. The main guide Emily was funny and knowledgeable. The experience was very smooth and safe.

Think twice about a bioluminescence tour with any company. We had 27ppl in our group and passed at least 4 other groups plus there were boats going by in the shallow narrow waterway. A bit crowded. BUT Kayaking at night through the mangroves upstream was fun and when we endured the mangroves and congregated in the open area, the stars above were amazingly bright; devoid of light pollution. Going back downstream was relaxing. Warning: the bioluminescence part was NOT like we expected; the marketing photos are NOT realistic. We had to put a tarp over ourselves to mimic complete darkness and then agitated the water to see a few sparkles. But the guides were knowledgeable and there were enough guides to help the beginner paddlers. I felt safe and still tipped them the customary amount.
